- Surprised at how fast my car is!?😲😲 Boostaholics GC8 got a Radium fuel rail upgrade! After I show you how to install, we take the GC8 out for a little fun. I take Orlando for a ride, then let him do some driving so I could work on the drivability aspect of the tune. This turned out to be very helpful, as I do not have access to a dyno locally.
Items I removed for more weight reduction:
Front sway bar
Battery
HVAC heater core
Plus mystery items...
I also improved my ignition map, added some timing, and modified the AVCS as well. I don't really know what kind of whp the car is making, but its safe to assume somewhere in the range of 550 to 600.
